Hey Ardee,

I think the main problem you are having is having the pectoralis connect properly to the deltoid of the arm. What you have now is the pectoralis stopping too short. If you look at the reference image below you can get a sense of where the pectoralis reaches all the way to the deltoid and how it moves when the rest of the arm does. The rest of the picture looks really good. I think the only other thing I would comment on is that the legs down look like they are firmly planted on the ground, unless you meant for him to hover. I would focus on having one of the legs being the weight baring leg. in this case if would be his left leg so the other leg would have the foot bent down a bit to reach the ground.

All in all i think this looks good and I would look at anatomy references for the chest if I were you.

Oh i see, i havent really got into detail yet by which muscles connect and which dont, i have only looked at references to get the basic shapes down. As for the picture you linked its a really good refereance, i will now in the future connect my Pectoralises to the delotid, didnt even recognize that it looked odd!

Dont you think that the back arm(the one behind the chest) is in a wrong angle? i got very irritated over this and i couldnt draw it right. Maybe it is in a right angle and im only confusing myself, i dont know.
Also, i see what you mean with the legs, this is a character drawn on paper so it is slightly rotated a bit by me who took the camera shot from a wrong angle. But i can tell that i didnt draw the legs in a proper weight balance. Since this was the first time drawing chicken or bird legs, i actually didnt know how to go with it, i guess ill have to look into the joints on bird legs aswell!

thanks for the reply brother, nice with helpful people!

Yes. That is part of what is going on. Another problem is you did not make the upper part of that arm long enough. Or you don't have the arm connecting in the correct place. The little "lump" you indicated above the far pec, the part that is not coming off the neck, is supposed to be the far shoulder. The way you drew the arm doesn't seem to align correctly with that shoulder and if is was connected it would make the upper arm too short.

For clarification "connected" is not the right term and could be misleading. When looking at real life examples and reference photos the pec and delt will sometimes look like they are "connected". In reality the pec is inserting under the delt but above the bicep. I feel this needs to be brought up even if the term is not taken literally. It would be very limiting to not find out why thing look the way they do.
