Thanks for the comment, I'll staratsya. As they say, everything comes with experience =)

Some anatomical weirdness in the length of the second dudes arms.  Some noticable pillow shading on a few parts (is the 3rd guy inside of a barrel/basket?)  Overall it's decent stuff, keep up your practice and work on your techniques!

Thank you! Well, yes, a little chubby =)

The last one looks a bit chubbier in the face than the reference, otherwise you've captured their likeness quite well. :)
