I really like the soft gradient one! I can only imagine how difficult pointillism could be on a tablet, so really my only criticism would be the same as most people have said - in general, just more shading, over a slightly bigger area (on the pointillism and cross hatching spheres).
EVALUATION FORM: Hi! This is Flaming-Noodle. I am here to evaluate your task for #Gakuen-Manga
STRONG POINTS -this is a nice starting point - good contrast on the 2 right spheres
POINTS to IMPROVE *The cell shaded one looks a bit rough, and is missing the reflective light near the bottom of the sphere where it reflects off the 'floor'. Also, the shadows seem to be the same color. Every shadow has gradients within them because of cast shadows and reflective light. It would be darker closer to the sphere.
*Pointilism sphere- the transition of the shading is very sharp and should be more like a soft gradient-but made of dots. The darker areas whould have dots closer together while dots in the lighter areas would be farther apart. This one is also missing the reflective light on the sphere.
*Soft Gradient- is much better than the top 2 spheres, but needs more contrast and darker values. Again, is also missing reflective ligh on the sphere and floor.
*Cross-hatching-looks nice in the lighter areas, but like the pointillism sphere-needs more of a transition between the dark and light values. The technique itself is admirable. Also, this sphere is missing reflective light.
OVERALL RATING of 5 stars Please revise this task.
Overall, its not a bad starting point, but it still needs alot of work. Some of the cast shadows and all of the reflective light are missing. Also, the transition from light to dark values is too harsh on the Pointillism and Cross-hatching spheres.
