Ok, I've played on your two maps. So, this is what I think about them.
Map #1 - Well, it's a good beginning of the campaign. We have a castle to build, it's a tranquil game. Yes, there are some assaults, but we can destroy them very easily. I didn't produce any bows, the reinforcements who come are enough to kill the brigands, or the spearmen. It was really easy, but I liked it. Somestimes, the facility is wearing, but, here, it was a sympathic game.
Map #2 - After producing some spears in the first map, we've here to defend the castle against some assaults. Well, here again, the defense is very easy. I've produced some archers, but killing the enemies was a very simple work. Even the catapult of the enemy isn't a problem. But it was pleasant too. The only reproach I have about this map is that it's too short. Maybe adding some other assaults more strong would be very useful, but, well, it's a good job. I think it's your first maps, isn't it ? A good beginning... Even if the maps are very easy, I was enjoyed.
Here, it's not necesary to make a review for each map. Globally, I don't unterstand the reason why you put "Hard" for these two maps ? Well, you're maybe a beginner, but I've played on maps which are VERY, VERY difficult. These maps are very simple. For instance, in the first map, I produced any bow, nothing at all.
Well, I must be honest with you. YThe two maps are quite... banal. In the first, we have to producing some weapons, and, in the second, to defend a castle against some few attacks. But, well, don't panick about that, you're a beginner, so it's normal. Be careful, I don't say you make a bad work, but, well, about the creativity, I already unterstand "originality", that is to say making a map which have some original points. It's not the case here about your maps.
Map Design: 4
Map #1 - Quite beautiful. I don't have the vocabulary to do a complete description (yes, I'm french xD), but, well, in a word, the hills give a beautiful aspect of the map, renforcing by the river crossing the map, and the marecage.
Map #2 - I very like the design of this map. It's a kind of bay very beautiful, especially the palce to build the castle, with the rocks who surround him. A good artistic work.
The stories are brief, simple, but, well, it's a campaign, so I think it's a proportional story, which become more and more complicated (I hope xD). Anywxay, sometimes, a simple scenario is better than a complicated scenario, which can be too complicated to be honest, which can be confused (but it's rarely the case).
A good work for a beginning. Don't discourage yourself if no one seems to be interested by your work !
