Re:What are your thoughts on my new routine?
Looks absolutely perfect to me. However if you say you're going for "size with aesthetics in mind", rather than strength, I would suggest making your rep range for most exercises a bit wider, possibly 8-10 or even 10-14, as I think the general consensus seems to be these types of rep ranges are more suited to hypertrophy, whereas the lower rep ranges (such as sets of 5) are better suited to strength training. You'll get bigger no matter what, but I think a higher rep range would be more suited. Just my two cents!
