Yes I can see what you mean, too much straight pipe with few bends/elbows once you leave the first part of the front pipework. In my personal opinion the first semi circle from the front cylinderhead is too tight of a radius which makes it look odd, also probably not helped by the exhaust outlet from the front head is further away from the side your pipework is going, unlike the rear cylinder. Of course the side rad will need taking into consideration I presume, otherwise I would say a bigger semi circle to start with, with it exiting higher up, me thinking the rad may mean you can't go higher up

What you have done for the rear cylinder looks a lot better than where you are with the front pipework atm, which is I think what you are saying (hopefully

). I'm not sure if that is any help

hopefully it is,
The question is are you going for the extra work/expense as a pipe bender
I'll give you 10/10 for enthusiasm though
