Awesome constructive criticism! One of the reason why I put those in here to hear insight from the best and veteran mappers. Just what I need to get better.
You know what, you are probably right. As I launch my first pserver, I just had the idea for my main town. A "themed park" or "themed areas" in Prontera. There is no single theme in the Prontera map, but plenty. Of course, I have zero knowledge with Browedit. Thus, I contacted Olrox to make a custom map for me. However, he seem to have plenty of ongoing projects and a few more people are on his waiting list. I do understand if Olrox a lil busy, I contacted him again after a month, but I could not delay my server's progress any further as I needed my server to be ready/be shared with close friends for bugs/exploits checkup. If i wanna be an RO Admin, though initially i had doubts, I had to learn the basics of map editing. I ended up studying Browedit myself.
I understand the importance of unity in design, but my idea creating this map is a "themed park" in prontera town. Not only a single theme, but different in each areas. The map idea is necessary as it matches with my server features as well. That explains why there's a lot of different modules added in that map. Thanks to Syouji's browedit tutorial in YT, i was able to study the basics of Browedit in no time. I was able to finish this Prontera Map in a week. I have not fully developed my shadow rendering skills, that explains the shadows in my map (and i love your tip, would def help me a lot in the future). Shadows & Lighting are still by far my weakest. Not to mention, I gave up adding custom 3D modules, as I was already on a rush and I thought that part would require me a lot of time. That explains why I pretty much copied the official modules. I do admit having limited understanding with browedit as of now, but this is my first map edit and hopefully I can get better in the future. Your insight will sure help me a lot in my future designs.
My only background before doing this map is Architecture and Interior Design, AutoCAD, detailed floor plan design of both interior and exterior building perspectives, Ergonometrics and proper scaling - but applying it in RO is a little hard and yet fun. It takes time to learn Browedit.
