Should I Do It?

[Neo Emolga]

This is your warning, it won't be much better. It'll look better than it did, maybe, but most likely you won't see much improvement since I have no way to do digital art beyond using a trackpad, and trust me that is not meant for art.

I have some advice when it comes to that, because these helped me MASSIVELY when it comes to improving my art:

• Reference pictures are your friend. Sure, you probably know what most Pokémon sort of look like already, but grab a reference picture anyway. Heck, I still grab them even when making Emolga pictures, and you know how many of those I've made. Find a pose of the Pokémon that's most like the pose you're going to use. It's bad to steal art, but using a picture as reference is totally fine.
• Sketch twice, then do final line art. Your first rough sketch is really just to get the pose positions and the body proportions right. It should mostly be basic shapes as reference to the sizes of things, nothing too crazy. Second sketch should be more refined to get a bearing on the details and to make sure you have a solid framework, and lastly, your final line art is what you're going to ultimately go with. I do all of that stuff in Paint Tool SAI, which rocks by the way.
• Find tutorials and try using them. I found this "how I do it" guide by @Liokora to be EXTREMELY HELPFUL. And there's a bunch on DeviantArt that are also very helpful and don't require excessive amounts of time and involve tons of complexity.

I'll admit, I haven't tried doing a comic series yet, so I can't say too much about panel layout and the storyboarding process, but I figured those would be helpful at least for the art stuff. Lately I've been able to do artwork that my younger self would have said "WHOA" to. The more you practice and the more you follow guides, the better you'll get.
