Try using several tools to create these different views, perspective, the mirror tool, using the strengthen line and curve line help. Had a hard time drawing the curve lines even using assistance. I'm also using an wacom intous 5 tablet trying to accustom to it again. I always feel drawings turn out a little soft. I kind of miss the blending mode for layers don't know if they are available. Main use the fountain pen for drawing and move the pen pressure adjustments. Use a color brush from the library to blend some initial sketches, use air brush for shading and a texture brush.
