Analyzing my game environment

I discovered difficulties with unity and the crops. Running through the crops there was loads of collisions and it was stopping the player from running in certain areas. For some reason the plain allows the player to run through it from only one side, so i were able to do it again and allow myself more time, i would have placed a plain back to back with another one, which would allow the player to run through both sides and carry this out through the whole crop field. I feel i should have created different textures on the floor and added in dead, pressed/stamped on crops for the floor to make it more life like. I could have added in more props around the terrain to show an obvious blockage for the player not to be able to get through and played around with the surface of the ground. The texturing for the roof of the barn i should have done again, and created more smaller roof textures and merged them closer together so the tiles were smaller rather than stretched out. Theres a white line on top of all the crops which is small but still noticeable which i should have photoshopped better. I feel i should have darkened the image of the crop itself on photoshop to give it a darker, more mysterious mood.
I was pleased with the overall mood i had set and feel the assets played a great part in that. The rolls of grass, the barrels, although i feel i should have made a couple with different textures. I should have created distractions around the house, maybe a garden and fence. And closed off the back of the house but felt it was necessary to allow the player to be able to see the game design from all aspects.
I was satisfied with the outcome, felt it had a lot more to do to it, and wasn't ready for a real game. If i want to improve on this i should manage my time much better and if i want to become a professional in this and any field that it's extremely important to be more organised, and manage my time well. As a first time game design i can be satisfied that it turned out to a minimum required level of skills, i can take this into account for year 2 and i'm confident of much better results.
