Constructive criticism -
You lack both a following seat and a following arm at the lope and gallop. Improving both of these will improve both your speed and your accuracy and get you working with your horse. You know this already because you mention the bouncing and working on improving it. Best way to work on both is at slower speeds, preferably on a lunge line, with an instructor to help you understand both the mechanic's of the horse's movement, rhythm and how you can work with it. It is very hard to maintain a following seat at speed - you need to be rock solid at slower paces before attempting it at gaming speed.
Your horse looks like a nice guy, willing and responsive who's capable of going to higher levels as you improve.
To Citrus - "nice critique" is an oxymoron. The dictionary meaning of critique is critical review or commentary, or a critical discussion of a specified topic. If you only want positive comments, you don't want a critique, you want fan mail.
The OP received some constructive criticism, none if it was mean-spirited, personal or harsh but it wasn't fan mail either.
I believe the OP was actually looking for a true critique, if she wasn't, she should have posted in the photos section rather than her.
