Just a little frustrated...

I'm giving myself 18 months to get this photography thing down. I know I'm making progress, there's just so much to get right - light, camera, composition, editing, etc. But I just keep making the same mistakes, and today it's focus (Tayler & Nathaniel, not quite focused). I'm sure it's because I was using my new lens - perfect for indoor shoots, but not perfect for group portraits like this one. At least I know where I'm going wrong, and I can try and fix it. I'm worried because I'm sure those 18 months are going to fly by and before I know it 2012 will be here and I'll be open for business.
