Hi Kales
Congrats on getting your channel started, a lot of people never get that far so good job!
Since you want honest feedback and most people who do are serious about wanting to improve their channels I'll happily chime in. None of this is meant to be hurtful in any way shape or form. I just want to help you
When I first came to your channel, I actually thought it was going to be a makeup channel, the banner style/colours along with the eye that looks like it's done in a very makeup style sorta way made me think that. I would change your banner to include something descriptive besides just your name. You could also add in which day or days you release videos so people can quickly see what your channel is about and when to expect new vids.
Next, your landing video you should make it a nice 1 minute long video that welcomes people to your page, states what you're about and perhaps list a few things people can expect from your channel. Keep it short and punchy, and don't forget to invite people to like your videos and subscribe to your channel. It honestly makes a big difference.
Next, early on it's ok to experiment with different topics/themes as you're figuring out what you want to do, but you should really hone in on your chosen niche and keep your videos as close to that as possible. If you're an art channel, then stick with anything and everything related to art. It confuses your audience when you change to off topic vids that don't cover art. People will get annoyed if you do it too much and leave you hanging! You have quite a variety of videos right now and that may be hurting you gaining more subs than if you stick with your theme.
Next, you need to keep your videos interesting and related to your main theme. I watched several of your videos and you have a tendency sometimes to wander off topic and it might be frustrating to some people who just want to get to the point (people can be impatient haha).
Next on the list, your comments. You don't have tons of them, but there's quite a few you've never answered. You should respond to EVERY single person who takes time to write a comment. I'd also recommend that you reply with other questions and genuinely engage people. You'd be surprised how much seeing a few comments with responses will create a favourable impression for people and it will make others want to engage too since they know you are responsive and friendly. Don't just say "thanks" to every comment. Reply with thoughtful responses and questions too, it will make a difference!
Next, your thumbnails. They need a serious overhaul. It's ok to use yourself in the thumbnails, but you need to pick a theme that fits your channel/style and then make fun and vibrant thumbnails that pop out. You can also use a lot of free editing software to add and deepen colours/change contrast to make them really pop. It will also make a big difference to your video views when people see a great looking thumbnail.
Your intro/outro - Keep them short and punchy, mention watching more of your videos and try to link topics from other videos into your current one and drop a link in the video as well.
Descriptions - Need a major overhaul as well. Make sure to work your keywords/phrases into your sentences, it can make a big difference as well. Use unicode (free if you google it) to make your sections stand out in your description. It looks great and it's easy to do.
There's probably a bunch more I could suggest as well but I don't want to overwhelm you. I hope you aren't hurt by any suggestions, you have a lot of good things going on your channel too!
Keep working hard on improving and you'll start to grow in no time
Blessings!
