Clip Studio on iPad has a pretty extensive brush set but I haven’t spent much time with their pencils. It’s very intuitive to use the pencils really have a rough look to them. I have been doing a few model studies to give a very natural media look to the illustrations.
Of course I did this months character design topic: motorcycle. The funny thing is all month I did a few rough sticky note character sketches and a few days before the deadline came up with a new concept and finished it all the same night.
