Looks pretty close to me. Before making a valid judgement on the tiller, need to know the unbraced profile and the front view. I don't see the issue you do with the left limb. Mid-limb out may be a little stiff on both.
Read some of Pearl Drums posts on using the straight edge. I have a caliper the has a 4 inch straight edge. I run that along the belly, getting the flat spots more rounded until there are no wide gaps or flat spots as I move it along the belly from grip to tip. I think you will see the limbs flattening out here as you move toward the tips. Might be appropriate for the shape of the bow though.
