As a general rule....if you can taste your fletching...you may be a bit too long in the draw

Unlock the Right elbow and put just a SLIGHT bend. This is actually a "stronger" position and more easily repeated for MOST people. This will keep your right arm from rolling the way it is in the picture.

Bow grip looks a little forced. When your get the bow arm in the proper position....the grip can be more easily attained and will feel more comfortable. Your somehwere in the "Medium wrist grip" gry area now...try to switch to low.

Here's a link that may help....pics and stuff toohttp://www.bowsite.com/bowsite/features/practical_bowhunter/grip/index.htm

Hold your right arm out as if your gripping an invisible bow. Look at the line that would intersect right down the middle of you forearm/wrist area...just to the right of your upward facing thumb and slightly off-center of the web of your hand....think SOLID bone on bone structure here. Try to forget completey about your hand and don't use it at all....try to get it so the bow is balanced on your wrist if you had no hand at all...

On another note...
The cable from your drop looks a little tight too...see how it pulls your cable forward a little bit? To much pressure on there for my liking...it'll wear fast with that much pressure and undoubtedly fail at the most inoppurtune time
