This might sound a bit cliche but my biggest influences for my comic TLC were Homestuck and Invader Zim
They were the primary media I watched/ read as a teenager and I started my comic when I was 16. For homestuck I liked the pixely style and thus I use a square brush to ink and shade, and use cell shading with flat colors. That comic is also what got me interested in creating a long term project
As far as Invader zim I likely picked up my thick lines style from them, and it was actually the cataliyst for the creation of my main character Yinyang! She was originally a black&white themed irken OC, then I decided to make her human disguise. I ended up liking that design better but she didn't quite look like a regular human so I decided to give her some powers to match her appearance. After that I wondered what other characters would fit alongside her and then I created a world to interact in. so if it wasn't for Invader zim my main character wouldn't exist!
I really owe it a lot to these two stories to have inspired me to be where I am today. not inly for the reasons listed above but because both inspired me to make fan art and thus helped me rapidly improve my art too so that I was ready to start tacking my comic when I did. I'm now 3 1/2 years in and i can't wait to see what comes!
