To make this effect disappear, it can be drawn like this or somethink like:

Just break the vertical lines at the top.

Yeah I'll try to fix it later thank you for the advice!

I hope this doesn't annoy you? If I have any criticism in the comments, then I will give an example of how I would draw it. But I could be wrong, this is just my IMHO.

Nah, I honestly want criticism because I've wanted to improve my art for a while which is part of the reason I made an account so if you have suggestions just say

Good. I usually draw with a 0.5 mm pencil, regular А4 office paper and a soft Koh-i-noor eraser. I also often draw outlines with a pen, but this is not necessary. I'm not very good at digital art, but if I'll have general ideas on how to help you, I'll tell you about it. Also feel free to ask me if you need any information. And feel free to PM me any time you want, you're welcome.
