>>5025813I tried my hand at this anon, sorry if you don't like the palette I went with. Some general things to note:
1) With cute, simple-ish designs, pay attention to your shapes and lines. For instance, you don't have to line the tiny hearts in the eyes, the star buttons, and the paw pads, because it just creates clutter for the eye. Simple, flat shapes read better for those! Also, the overlapping eyebrows is also a bit of a clutter to look at for me personally, so I would avoid it, but I get that it's a style thing.
2) Your colors are a bit muddy, like the yellow outline and the pinks you chose. I think overall you need some more saturation to make your colors pop, and you need more contrast (they look a bit samey at the moment, which doesn't read well from afar/thumbnails.
Judging from your style and reference, I'm assuming you might make merch? You should push your saturations otherwise they turn out even muddier when you print them. Also, /cgl/ has a good artist alley thread!
3) Too many of the same motifs (ribbons/bows) in the same image, and clashing patterns (polka dot, gingham, the heart pattern bg) too many of these together reads a bit messy in my opinion.
4) If you're going to make an outline of the character, it's better to either have a consistent stroke applied or block interesting shapes out to separate your character from the flat bg.
I think this is really cute and I can see the appeal! I think mainly I would focus on increasing the contrast and avoiding picking muddy colors (go further with the saturation scale!), and work on simplifying shapes + make interesting shape designs. Hope this helps, anon!
