I like it James. Great proportions, appealing shape. I like the slight forward taper of the barrel end where it goes into the endpiece. I know that makes it more comfortable to hold.
Hard to judge on size. How long is it? Does not look too big? and even if it is 'longer/larger', a lot of people prefer a heftier call, and if that is what you like to make and offer, then that is awesome!
Makes me think a lot of the proportions of my own calls. When I was turning in the 90's, I made two versions, a shorter 5" call which was quieter and suitable for days in the woods and days with bad overcast. I also made a 5 1/2" to 5 3/4" long call with a larger diameter endpiece. This call was much much louder, suitable for fields and clear bluebird days. The two calls had a completely different exhaust treatment, and I used the different lengths to make that happen. The longer calls now just feel huge in my hands and I've not turned any since I've been back turning. Funny what a 15-20% difference in length can make in the proportions and feel of a call!
