Congrats! It does feel great, doesn't it?
How much clothes did you take for two days? And what kind? What kind of clothing do you ride in?
[edit] Just looking at your pics now. If I can suggest getting an inflatable sleeping pad instead of the one you have. They're light and small to pack, we have Therm-a-Rest ones.
And when buying a sleeping bag, look for something lights and small when packed. We got goose down and even though expensive, they're super light and pack into a surprisingly small roll, when compacted.
I don't know the area, but did you really need to bring that much water with you? There was nowhere to buy/get water along the way? That's a lot of weight, unless going through really remote areas, I think you can just take two or three water bottle mounted on the bike and maybe a 1.5 litre bottle as an insurance.
