First off and most important in my book, congrats on getting your feet wet!
First project is always the hardest.
The trunk movement is not bad, but lacks a bit of taper, which seems pretty common for junipers. I think the bottom branch is too low to match the current styling - informal uprights typically have the first branch with the first bend - but following the last comment, I would probably leave it as a sacrifice branch to help with the taper.
Re the branch coming straight out - I don't think it works there, branches coming straight out almost never do. It's hard to tell from this photo if it's coming off close to the branch below it, or more halfway between the one below and the one above. You might be able to keep it just by rotating the tree a bit if it's not too close to the other branch. Also, are there any branches on back? Make sure you put some nice movement into the branches now, it just gets harder as they thicken up.
I think if it were my tree I might try increasing the bends on the trunk. Not that there's anything wrong with the standard subtle S curve if that's what you want, but I think the overall tree would benefit from tightening some of the bends up.
Plus, the heavier bending is kind of fun. Get somebody from your local club to help you with it and you'll learn a lot.
I'm still close to a newbie myself, so take that into consideration especially as more experienced members start to weigh in. Overall, great job for a first try!
