First, you need to decide if you wanna be a bowyer or not, because in all honesty, piking, and heat tempering should be paired with careful retiller ing of any bow.
Regarding the bow itself. The bow is not terrible, but the tiller does not look spectacular, bottom limb is weak slightly and not tillered perfectly IMO. The bow is clearly too long for 29" draw and/or 40#.
Regarding the archer. You are not hitting 29" I suspect. Put a clothespin on your arrow shaft, and draw the bow using the back of the bow to pull the clothespin as you draw, then let down, and measure the position of the clothespin. This will tell you how far you are drawing. Or get a friend to measure while you draw, or just to mark your arrow while you draw.
If it were my bow I would: pike the bow to 68" ish. Narrow tips. Retiller as necessary. Then heat temper. Then check tiller and fine tune as needed. But I'm not going to lie to you and tell you that all of that is an easy slam dunk for a first timer.
I might consider seeing if the bowyer would tune it up for you before considering a drastic series of moves like that.
Be nice and he won't take it as an attack on his work.
