There are still some joints with a 'lumpy' appearance. These are 'cold' joints. The ideal joint should be smooth and have a cross-section as in the diagram below. Some of the other joints have a 'frosted' appearance. This can also be an indication of a cold joint, but it can also just be due to using lead-free solder. What kind of solder are you using?
You should be able to fix these up. Just take your time and use a clean-hot iron. Clean your tip after every few joints and give it a chance to re-heat. This is especially important if you are using a low-powered (25W or less) iron.
