Cuboodle, I have to agree with what every poster has said so far. If that is your first attempt, I say it looks absolutely fabulous for a first attempt. But it does look like your chisels might be holding you back. Remember that practice, even when it doesn't turn out right, is your friend. Practicing on curved surfaces is even a better friend. Try carving on half of a 3" sphere, or 3" hemisphere, and you will know what this means.
When I carve, I expect my chisel to feel like my pocket knife going through a chunk of parmesan cheese... There is resistance, but it does slide through. If it doesn't slide through, I know I am trying to go to deep. If it glides along much easier, then I am too shallow, and will have to sharpen my chisel much sooner. With practice, you will get a feel for this. But this requires a skill that is extremely important, and that is:
Very sharp chisels! You must learn to sharpen a chisel to scary sharp condition. The last straight razor I bought took me one stroke to realize they didn't know how to sharpen a razor properly at the factory. But in order to carve you must learn how to sharpen, and keep you tools scary sharp. Gravers are the same way, but much different in their sharpening. But that is another subject.
How are you sharpening? Are you honing? Once you conquer sharpening and honing, your carving life will be much, much easier. I see some chip-out in your background, which tell me you are either cutting in the wrong direction, or your tools aren't sharp enough. I also see some hard lines in your curves... What size is your stabbing chisel? 1/ 8" or 3/16"? If so, use a smaller one. I use a 1/16", and still have to compensate for chisel width in tight spots.
I do like the artistry of the rough carving though. Is that your own design? I would invert it though if I were to actually try and put that on a rifle. As is, it is hard to put in the somewhat triangular area of a buttstock. But keep up the practice. You are talented enough to do this. Thankfully, I don't have any pictures of my first attempts. They were worse than yours by a longshot. Keep practicing.
