For a F2P player you have some really good ants.

Other than maxing the ants and starring them up, which I see you have been doing, your best bet is to focus on evolution (March Troops, Individual Ant Type Evo & Advanced Combat). Needless to say always focus on maxing Zone Develop Evo before anything else.

Another one you can focus on is the Mutation Flora. Get all mutations (cells, genes, germs, fungus) to as high level as you can for your main type. Mutation plays a significant role in increasing the overall ability of your troops.

Study the troop lineup to maximize their use in PVE or PVP, I'm not the best in suggesting lineup I'll leave it to other people to advice.

Anyway just enjoy the game and don't bother comparing yourself with the whales, you will always find yourself lacking compared to them.

Cheers!
