One of the best droid paintings I have seen here. What I like most is that the design is well thought out. Every joint, part, connection seems to have a purpose. It looks like it could function. Not many artists accomplish something like this.
The painting style is crisp, clean with great sense of lighting. The colors of the antagonistic greens and reds are well chosen, making the main subject stand out well.
Okay, now some tiny crits
The feet and legs are hovering a bit, I would suggest to do a heavier shadowing in that area and darkening the casting, indirect light *line* on the feet a bit.
The perspective is a bit off (noticably the computer parts behind 'her'): it's slightly off, baerly, but because your painting style is so terrifically clean it stands out a bit
This is a painting well worth a DD and should be viewed by anyone appreciating great art
