I've been attempting to doodle or sketch at least one image not related to commissions a day as a way to make myself more confident in drawing stuff for myself again, but haven't been uploading them to FA. So I figured I'll just do the occasional dump of images after a sizable number have been done each time.
There's a lot of sonic stuff in there...
I really like sonic stuff...

For reference, the majority of these images took around 1 hour each (except for the uncolored sketch, which was a quick 10 minute doodle before I had to go to sleep early)
