First Time Instagram Journey !

This is my first time trying to grow an instagram account(s). Hoping to reach 5k by July on any account I try. Any tips would be appreciated and new niches to try. Doing this by hand, no bots as of yet.

Day One:

Account 1 ( Animal Niche ): 332 Following | 122 Followers | 5 Posts ~36% Followback
Account 2 ( Luxury Niche ): 259 Following | 81 Followers | 5 Posts | ~31% Followback
