Mangas,
Keep it coming!!


Now you're getting into the hard part IMHO-shadows and highlights.
For your consideration, try making the shadows and highlights consistent in sun direction and intensity. The shadow behind the cowl is too intense and not in agreement with the sun direction and intensity on the shadow under the tail. The tail shadow appears to be too narrow and too curved. The cowl flaps need shading as they appear 2-D now.
Finally, the upper prop blade highlight is bending in the wrong direction-I believe it should be along the leading edge of the blade for shaping.
Impressive start!
