Great sketches, some are a bit messy and it's hard to tell sometimes what's exactly going, but nonetheless they have a certain appeal and volume to them, due to the extensive crosshairing. I like the oil painting of the woman body, for an one hour painting it looks like you have all the necessary info down! keep it up!
Well, I've kinda sorta begun tackling the digital realm, but time's a precious commodity, so hopefully I will have more of it in the near future to flesh out this skill set, because these are just the tip(of the tip) of the iceberg, so wish me luck!
(These are literally the first three I did after getting my paws on some sweet MB tutorial vids.)
