I agree with Morgan.. it does seem that your pendulum has swung a little too far the other direction! That said, I actually love how you've used moss and shabby together -- your photos are now all very cohesive and I would know it was you! Before you change too much, you said you had a new computer -- Mac? Well, in whatever photo program you use there may be a straightening bar. Some of your photos were tilted and this can fix that. I would also recommend trying a little lighting from the front or above-front. I live in Oregon and can't depend on indirect bright light all the time so I use full spectrum CFLs (the curly ones) inside those cheap hardware aluminum workshop lights...they don't get hot. Not all bulbs are alike, tho, and can throw off your white balance. Oh, and are you getting familiar with your new camera and whatever white balance feature it has? Experiment with that and take notes as you do so you can find the right settings. Your banner. For the time being you could just change the background color to be more cohesive with your mossy shabby gray. Your shop name is great! I wish you would sophisticate the look of it in your photos, though. I think it's a little too big and too word process looking.
I love your avatar photo! If that's you, we could have been in 2nd grade together! :o)
Of course, I should talk about any of this! This one's my very slow to kick into gear new and 3rd shop and the other 2 aren't wildly successful or anything!
Keep having FUN! I think you are totally getting there.
