Bead Brooches

Before I start, I'd like to say I'm not very good at beading (yet - I'm being optimistic!). I'm just trying to figure it out, and I'm not being 100% successful in what I do. If anyone out there is good at beading who wants to give me some tips then please feel free. I'm going to keep practicing though, and when I start making more of these I think my main plan is to plan the image as a pixelated picture before I try to put the beads together.
