See... the issue is. MCreator isnt liked on MCF. If you use MCreator to make a mod, you didnt actually make the mod. The mod was made by the creator of MCreator and you just quickly clicked something together and added some textures which I doubt you even made yourself (for most of them - the ore was you I'm sure). If you want to gain attention and appreciation in the modding scene - take this from someone who has been in the scene for over 9 years: learn Java, code the mod yourself. There is no effort involved in putting together something in MCreator, hence why its frowned upon in these forums. Learning java and how to do forge mods properly not only allows you to do alot more stuff in the long term. Its also YOUR achievement and will feel alot more rewarding and get alot more attention from the community. There are plenty of modding tutorials out there as well. You start simple and work your way to become a good modder. You do not go onto MCF, post a mod with MCreator and call it your first mod (because it isnt stricly speaking even your mod at all), and then ask for feedback. You will hardly get any, and IF its most likely just gonna be a comment saying "MCreator :/".
I think you got a concept for a nice proper first mod there with the enderfish. Call it infested ores mod (and code it yourself), and give every vanilla ore a chance to spawn a [...]fish mob when mined without silk touch. Add to that some nice drops to those mobs that are useful but not overpowered and voila, you got yourself something thats presentable as a first mod and might collect a number of downloads and some decent feedback.
