very cute artwork you have here! I dont know much about drawing creatures and digimon but i will do my best to give a critique
the main critique I have with this is the thin black lines, like the horn and the mouth are a bit shakey you can correct that, if you have a tablet, with changing the photoshop settings to autosmoothing lines. If you dont have a tablet, the best thing to do would be to blur the lines or use a brush setting that changes opacity automatically towards the end, there are alot of those types of downloadable brushes on deviantart!
Other than that tiny thing though you've done a lovely job
Hii Thank you! I'm new to this all digital art thing and this was my first digital drawing , but thanks for the autosmooth option tip! Thank you for the awesome critique and for the given time to make it ! :3
