Strange proportions
Well, this piece is certainly built on weird proportions, with the guy';s nose being almost the same size as his pink fluffy bunny-clad feet. I like what you've done with the body hair and the way you've faced in the look of the stubble, with the more visible hairs poking through.
The main thing you can do with this piece is use better quality (sized) tools for the job. Draw the outline very roughly and then zoom in and edit using a thinner brush, so that it looks neater - when you zoom out, you'll really see the results in a very positive way.
You've done a decent attempt at a background, but straight lines are needed for the walls meeting the floors - skirting boards are a way to get a little more detail into this picture for relatively little effort.
When you're doing colouring or shading, please try not to go outside of the lines - this might be helped, by drawing in the colours you wish to use and then doing the outlines last, to tidy everything up?
