It's good and all but the telescope is a bit awry. You've mounted it onto the bending limb of the bow rather than the static handle. Every time he draws the bow or releases it the telescope moves ruining the point of aim thereby ruining accuracy. It's also crossing in the path of the string if you notice it's perspective.
yeah I did take that into account (though that's not the point) - actually the telescope is mounted into the central part of the bow, and on the vertical axis, which will be fixed and only the extremities will bend - but yeah it's just a sketch, and besides it's a metaphor so don't look at it as a character - the dynamics won't really work anyway - since even the lower part is kinda blocked by the right leg - as in: it won't be released freely as I said my works are rarely functional characters, but rather ideas/metaphors - so you shouldn't really look for functional consistency
