Hay there Bud.
This is a great start, though there are some things id like to point out.
- The lats dont go straight up from the side, they tuck under the the arm pit which actually attaches to the humerus bone. Ill try provide a reference later today, but below is an image.
This is what the lats should do.
- your abs are way to big and stretch out to far. they should come in more its more of a narrower colunm downwards.
A good thing to do is start the chest, then sculpt in the rib cage. Just a simple egg shape that starts righ under the chest and goes to about halfway, then back up in an art to the back.
I hope this diagram below can help lol.
- With regards to the image about the ribs above, Now phill in this area in Purble so that its almost like a rounded shape.
Dont worry about those interlocking muscles right now (External Obliques), Just get the fundamentals then do that later with a detailed pass.
If non of this makes sence, Sorry man, Perhaps we could do a screen share ? I could show you then the fundamentals i have been learning.
