You stand to do better if you space out the timing in your posting schedule. 2 posts in one hour in one community is generally considered spammy. I think both posts featured high quality photographic content but try to keep that in mind. 2 posts in one day is probably fine if there is effort and quality photos in the post... but 2 posts in one hour is not a good habit, even if you have the best quality content. Keep up the great work and glad to see you posting again in the community. Cheers!
