Yeah, like Geoge says. You don't just heave it back, you tease it back slowly, correcting any problems before they get too big.
Like that right limb, it may be fine, but it may try to bend sideways (towards us in the pic) as it comes back. Have a look down the limb and see if it is trying to bend, maybe thin out the edge nearest us a tad.
Anyhow, take your time. Is that a short string on it (e.g At a proper brace height?) if not, then get a short string on it before you take it back further.
Theoretically you keep pulling it back to near your target draw weight, removing wood to slowly increase the draw at that weight until you get to full draw at target weight.
Good luck, some times you can get a twisted limb to pull back perfectly ok as you draw the bow, but it needs some care and attention like maybe moving the nock sideways a bit.
The bow I currently working on as one limb which tries to bend sideways.
