Eh, there are some decent shots, and the color really stands out in a bunch. But I think that you should try shooting something a little more exciting, or change your perspective a little. Like with the flowers shots, I've seen millions of flower pictures from the side or head on, heck, I even shoot that stuff. But If you're serious about developing your photography try and spice it up.
On a side note, the bike shot is sick, I just wish there was something in focus.
Good luck, you seem to have a good eye.
