Hey there! Your figure work has improved quite a bit but I really like your digital paintings! Especially the helmet on the last page, that looks great. You have a very good grasp of metal and reflections.
Oil painting? That seems like quite an achievement if you have that little experience with the medium. Impressive.
Those figures are improving rapidly. One thing you can notice from comparing the poses from imagination with those from life, is how some of the last ones are more 'comfortable'. Try and feel for yourself if a certain pose would be tense or at rest, stable or in motion. I believe consciously thinking like this is a great help. Not quite sure if you're learning from a book, Bridgman mentions 'rhytm' and 'flow'. There's more to a pose than anatomy alone! Although now that I'm typing this, I notice how the last ones are much better.... Keep at it!
Think the digital portraits in #268 are very well done. Something really happened here. As if you got the right feel, or learned something new. But you probably know better yourself.
In general you can see a shift in those portraits. Sometimes those heads were too thin or had too little structure, but its happening less and less...
