This is great! Shading looks good; The lighting and different colors for the eggs is realistic; The brush strokes are very pleasing to the eye. From an artistic standpoint, this was very skillfully done! My only problem with it, is that the paper looks rather crinkled, diminishing the quality of the painting. I don't know what you used to upload it (a scanner or maybe you took a picture of it with your camera or phone camera), but those unsightly little kinks in the paper really take away from what this could be.
Keep up the good work! Your painting is very good, and it can only get better!
