I like the bow. I like the tips, the arrow pass and finish work.
But since you asked for a critique.
(I sat through many of my wife critiques for art school, terrible events... You spend hours and hours and some schmuck rips you open, in the name of 'art'. Most of the time it was minor, personal opinion and inflammatory... Not my intention in the least)
You possibly could have got away with a little less length but then again I dont know what the purpose of the bow is.
If the bow gets shot alot, the arrow pass; which is awesome, will wear quickly.
And last but not least, the bottom limb could be just a bit stiffer. You can see it is bending a bit more via the mortar line on the wall behind you. How you are gripping the bow could affect how the bottom limb looks, it may not be weak, possibly just a visual.
Just remember, I like the bow.
I dont usually post unless I do...
Oh and one last thing,
your photos are good, composition wise. Except one or two...Composition is an important thing in my home.
Damn you art school!
