Meanwhile, back at the ranch.....
With regards to your rifle, not bad for a first timer, need to improve some and that happens with doing more. Nice thing is the more 'mistakes' you make the better and quicker you learn (supposed to be that way, but I'm somewhat slow).
The cheeckpiece side needs help....looks like there is enough wood on there to re-shape it into a nice gentle sweep and undo those harsh 90 degree angles...but that's just me. I'd also undo as best I could the carving detail... it really isn't needed, but that would take a bit more experiance, which is gained by doing and making mistakes (viscious circle).
If you can, depending on your location, visit Friendship and hang out at the gunmakers hall. Watch and talk to Dick Miller, look at his cigarbox of tools, handle them, ask about them, watch how he uses them. Dick is a very generous person and is so open to questions and really appreciates interest in the subject matter. Go to Dixons if you can and do the same.
Put this one aside for a later time, build and learn, then go back to it if you wish and see if you can make some improvements....I know it sounds perverse, but if you take the approach of thinking: "It's jsut a peice of wood and there's a lot out there", then a lot of anxiety goes right out the door, it makes building easier to do and a lot more enjoyable.
Getting back to Dick Miller....I would ask him where in heaven's sake did you get these tools? His reply was: I made them....the light came on! Most of his tools are remnents of needle files reshaped, tiny little home made chissels in a walnut shell, all sorts of things. He had to make tools to do the carving and work he was doing. See, there is not any one source for tooling to do some of this, so you need to use your imagination to make some of these. When you get to that point, the fun really starts.
Good luck with future stuff.....
