Drawing a compound is fairly different to drawing a longbow, or a warbow. With a compound, the draw is stacked at the beginning of the draw, and becomes easier as the draw goes on. With a self-bow, the draw is stacked towards the end, so it begins easier to pull, and at the end it's far harder, especially if you're not using your shoulder muscles correctly.
They also have different draw lengths - for insance, with a compound you draw up to your chim, and with a longbow you draw up to your lip. With a warbow you draw at least as far as your ear.
So a heavy compound bow is far easier to draw than a heavy longbow. I've never tried warbow archery, but I can pull a fourty-five pound compound bow without problem, but a thirty-five pound longbow is a ***** to hold at the draw for more than a few seconds.
You probably already know this, but there's also the matter of not locking in your elbow. If you grip the bow normally, then the bottom of the inside of your elbow will stick in, where the string wants to fly. It'll get hit, but because of totally different reasons to the string hitting the inside of your fore-arm near the wrist. Because of this, in target archery you need to at least relax and rotate out your elbow. If you're using a heavy bow then you also might damage your elbow, especially if you have it 'locked', but then again you might get Little Leaguer's Elbow anyway if you're practising a lot when you go through your teens.
