Hi hi! Cute idea! The colors and render are a little unpleasant and need a final polish, but other than that, I would not say the design is poor. It comes down to experimenting and drawing inspiration from other people. Here, you made good use of linework while maintaining a graphical rendering style. Now that the base is established, you can combine cell shading and inking to add rendering over top. You can also include textures and color variations. It will enhance the overall quality of your artwork. Extending a canvas to a full picture can also be intriguing. Here I made colors more bright, colored the linework and made it more bold. The black linework made it a bit muddy so be careful how you treat lineweight. Pick a more solid brush and avoid painting if you want to have quality linework. In the end,is up to you how you vision the result. To me, this can be turned into a cool sticker! Hope it helps! | Artwod Feedback
