Here are some of the Obras I made with different style and medium some are Hatching and some are pure rendering . I used the free-hand technique to improve my way of drawig anatomy and to have a better scale of a Painting or anything related to art. 
This one is a Ballpen art of mine which took me only 30 min. to finish. What I did here is i used the Hatching technique and this is the painting of juan luna titled ( Spoliarium).
Commissioned Artwork from lastyear probabbly the best one. I used faber-castell classic colorpencils in a rough paper .
The model schazna Laparan my favorite girl HAHAH dreamgirl again ballpen art, this time more on proportion of the anatomy is focused here.
So this will be my first samples, I'll be posting more so stay tuned .
your work is amazing! Keep posting, hope to see more of your art.
