Hello! I’m a very experienced 2D designer and I’ve seen an extremely common error in many other GFX designs: the consistency
I don’t know if you made the drawings of your icon; but here’s what I mean:
You always should try to use the same size of pencil and outline on all the pictures that you draw; or at least trying to do so. The only exception could be the text that needs to be eye-catching and it can be a bit different from the rest. Also; the background have the same problem; it doesn’t really match with the rest of your image.
I would also give you the advice: If someone ever commission you; you SHOULD NOT use any google images (maybe just for reference is ok); because if your customer finds out that you used free images, he could be really angry and rude at you.
I currently use Photoshop to work; but I also started using Pixlr (even before there were two versions [Pixlr E and Pixlr X]) and really think you could do better if you keep practicing.
Overall; it’s a really good job; you just need to practice and keep gaining experience. Hope it helps!
