Good job so far, the colours are well balanced altough some are a bit too faded, the proportions are good (

) but you have to work a bit on the weight problems. For example in Learch Portrait 3 you have that line that defines the top-left corner of the picture. That could be moved to the lower right corner to balance the weight towards the middle (the center of atention is shifted a bit left in that case). Also, you could improve your paintings by adding lines that help defining the primary and secondary (if any) centers of attention.
For example the karan painting id pure genious as far as balance and center of attention defining is concerned.
Here you notice that there is a primary CA, the kran, and you can see all the red lines pointing towards it, and a secondary CA that is the tree on the right (cyan lines help defining that).
A little improvement would be required to battle scenes, or scenes that involve movement (like the \"Menki in battle\" picture). Those require oblic lines (I don\'t know, maby you could add some oblic skews) in order to give a dynamic impression.
I\'m looking further to see more paintings and sketches
