personally I think you've done very well.I like the composition and think the picture reflects what religious imagery is supposed to reflect,that is a point of meditation to picture while reflecting on faith.I do not have any organized religious beliefs,but I think the figure accuratly depics the nature of crist as proposed by christian dogma.you're grandmother is bound to be thrilled. my only 2 thoughts would be 1st,think about doing youre signature in blue and making it a little more subtle,or blended into the background,and 2nd,and I'm not sure about this,but I thought the spear wound was on the right side of the body.nice work,good luck.
